ZebraIMG: Import Zebra (rf) format
Access this help text as a web page: ZebraIMG
Presentation and options
This application allows the import of files in the internal raster format of the Zebra software to the format of MiraMon. This format is used principally for satellite and radar images in the meteorological field.
For more information on the specifications of this format go to: https://www.eol.ucar.edu/software-center
Although the MiraMon raster format requires the same resolution in both
dimensions and, therefore, squared pixels, the program
allows importing RF rasters with non-squared pixels. In this case
a bilinear geometric correction is performed to resample the original data
to a net of equally spaced square pixels with the side equal to the smaller
of the two dimensions of the original.
The program also allows the original raster to be transformed
geometrically to a chosen reference system. In this case it is necessary to
identify the original reference system from amongst those reference systems
supported by MiraMon, and to choose the output system for
reprojection.
It is also possible to choose not to reproject, and the program will
document as the reference system of the output raster that system that is
the default used by the Zebra software. This is an equidistant
cylindrical projection in a spherical model; the center can be defined in
the users geodesic tables.
This version does not support multiband input rasters. If the same raster
can be obtained in GrADS format then this can be correctly imported with all
the channels to MiraMon format using the application GrADSIMG.
Dialog box of the application
Syntax:
- ZebraIMG Option InputFile OutputFile [/SIST_ORI] [/SIST_DEST]
Options:
- 1. If the user does not wish to reproject the original raster, or that the original reference system of the RF file is kept.
- 2. If the user wishes to reproject to one of the other reference systems supported by MiraMon. It is necessary to correctly identify the datum of the original reference system.
Parameters:
- InputFile
(Input file -
Input parameter): Is the file to be imported (assumed to have extension rf).
- OutputFile
(Output file -
Output parameter): It is the raster output file.
Modifiers:
/SIST_ORI=
(Reference system)
Indicates the identifier of the reference system of the RF file. The default value is that of the reference system of the Zebra projection (cylindrical equidistant) identified as Zebra in the equivalences table u_idofic.dbf. (Input parameter) /SIST_DEST=
(Output reference system)
indicates the identifier of the reference system of the output file. The default value corresponds to the RefSystem= key in the [Metrica] section of the MiraMon.par configuration file. (Input parameter)
